Upon this axle 28 a chopand referring especially to Figs. 1 to 3, 1-repping-tool a0 is rigidly mounted, the same comresents the frame of the cultivator,which comprising a hub 31 with curved arms 32, to the prises an elevated cross-bar 2, to which oppoforward faces of which hoes or blades 33 attach 8 5 sitely-disposed standards 3 are attached, said by means of bolts 34. One of these hoes is 4- standards carrying horizontal arms or spinvery clearly illustrated in Fig. 5. Each hoc dles i at their lower extremities, which prois provided with a pair of slots 35, disposed ject laterally and horizontally in order to fasubstantially radiallyin order to enable the pocilitate mounting the implement upon wheels sition of the hoes to be adjusted radially with 9 5, as shown. This frame 1 comprises rear respect to the axis of revolution. As shown extensions 6, carrying cultivator blades or most clearly in Fig. 4:, the forward edges 36 of hoes 7 and suitable handles 8. At substanthese hoes project below the rear edges, so as tially the middle of the crossbar 2, referred to facilitate the cutting and removing of the earth, it being understood that as the implement advances these hoes are rotated continuously over the cotton, so as to chop out portions of the rows of the plants in the wellknown manner.

The side-bars of the chopper-frame 18 are provided on the outer side and near their front ends with attachments 37, having lateral curves or projecting portions 38, which form loops or keepers adapted to receive the vertical guide-rods 13, as shown in Figs. 1 and 3. These loops fit loosely on the guides 13 and are therefore adapted to slide easily thereon. They constitute the means of connection for the draft devices between the chopper attachment proper and the frame of the cultivator. It is obvious that the chopper attachment is thus free to move vertically or rise and fall independently of the cultivator wheels 5. Thus the four wheels 22 and 23 of the chopper attachment and the frame 18, connected therewith, work vertically and independently of the cultivator; but the front wheels 22 will take hold on the soil, so as to communicate rotation to the choppers 23. It is found in practice that where the ground is in a very soft condition the wheels 22 sink in to a greater depth, so that it may be necessary in certain instances to adjust the hoe-blades 33 radial, such adjustment being possible by reason of the elongated openings or slots 35.

For the purpose of enabling the implement to be drawn along by horses a cross-tree 39 of any suitable construction is attached at the rear of the pole and preferably forwardly with respect to the guide-bars 13, swingletrees 40 being attached to its extremities, as shown.

In actual practice a lever of common construction will be arranged to enable the chopper to be raised in turning corners or in going to and from the field. 7

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with the wheel-frame having a suitable draft attachment and provided with vertical guide-bars arranged at the front and spaced apart, of a chopper attachment comprising a rigid frame having loops adapted to slide on the aforesaid guide-bars, and having pendent hangers, transverse axles having bearings therein, wheels mounted on said axles, and a bevel-gear keyed on the front axle, a horizontal shaft arranged lengthwise between the pairs of wheels and geared with the aforesaid bevel-gear and provided with choppers proper, and pendent hangers in which the chopper-shaft has its bearings, substantially as described.

2. In combination a main frame, wheels supporting the same, a tongue attached to said main frame, a cross bar attached to said tongue, guide-bars attached to said cross-bar and extending substantially vertically downward therefrom, braces connecting the extremities of said guide-bars with said tongue and said main frame, a chopper-frame disposed between said guide-bars and having loops receiving the same, a chopper-tool carried by said chopper-frame and rotating upon a longitudinally-disposed axis, wheels supporting said chopper-frame and means whereby said wheels may drive said chopper-tool.
